We're too crabby!
Look at what we found in our backyard. Can someone explain how we could have crabs in Africa when we are nowhere near the coast?

The same way we have seagulls in Hickory -- 300 miles from the coast?
probably dropped by a seagull headed inland for a vacation
Evan you live very close to one of the most interesting bodies of water in the world. Copied the following from "http://www.tourzambia.com/natural-resources/lake-tanganyika.htm"
Lake Tanganyika’s waters lap Tanzania, Burundi, Congo DR and Zambia. It is the longest fresh water lake in the world and the second deepest after lake Baikal in Russia. The immense depth is because it lies in the Great Rift Valley, which also has created its steep shoreline. It reaches a depth of 1433 metres (4 700 feet), which is an astounding 642m below sea level.Regarded as one of the most biologically unique habitats on earth, Lake Tanganyika is also an evolutionary showcase due to its great age and stability. Ninety eight percent of the lake’s cychlids (which comprise two thirds of all the lake’s fish) are unique to Tanganyika. Also endemic are all seven of its CRABS.
Evan I also found this info...
There are around 100 species of freshwater crab currently recognized from Africa (Dobson 2004) of which over 1/3 are found in Eastern Africa. Most species are associated with flowing water. The importance of detritus in the diet of most species suggests that they are the key shredders in African rivers. Crabs also provide a valued food source for a wide range of predators and the basis of some small scale fisheries.
